Continues Integration & Deployment

A brief introduction

Definitions

Continuous integration (CI) is the practice of merging all developer working copies to a shared mainline several times a day.

With continuous delivery (CD) teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently.

Continuous deployment (CD) is the next step of continuous delivery: Every change that passes the automated tests is deployed to production automatically.
